LAM P-eu RNR ATTACHMENT.

SPECIFICATION forming part of Letters Patent N o. 748,889, dated January5, 1904.

Application iled May 15. 1908.

T a/ZZ whom t may concern:

Be it known that we,WATsoN B.- STOCKMAN and JOHN F. FRIEL, citizens ofthe United States, residing at Chester, in the county of Delaware andState of Pen nsylvania,havein vented certain new and useful Improvementsin Lamp-Burner Attachments, of which the following Ais a specification.

This invention provides a simple attachment for the ordinary form ofoil-lamp burners for extinguishing the darne after the wick has beenlowered or in case of accident to instantly extinguish the flame thoughthe wick be turned up to its fullest extent.

The attachment is adapted for application to the type of burnersaforesaid which are in use or may be applied to them when placed uponthe market.

For a full description of the invention and the merits thereof and alsoto acquire a knowledge of the details of construction of the means foreffecting the result reference is to be had to the following descriptionand drawings hereto attached.

While the essential and characteristic features of the invention aresusceptible lof modification, still the preferred embodiment of theinvention is illustrated in the accompanying drawings, in which- Figure1 is a perspective view of the burner, parts broken away. Fig. 2 is avertical sectional view showing more clearly the operation between thepresser-bar and the extinguishing-sleeve which surrounds the wicktube.Fig. 3 is a perspective View of' the presser-bar removed.

Corresponding and like parts are referred to in the followingdescription and indicated in all the views of the drawings by the samereference characters. l

The attachment contemplates the provision of a hollow wick-shaft 1,which is applied to the burner 2 as usual and which is provided with thespur-wheels 3, by which the wick is operated. The burner-cap 4 also isillustrated, and the finger-piece 5 of the wickraisi'ng shaft 1 willalso be seen to be of the type commonly employed for this purpose. Thehollow wick-receivingshaft 1 receives a reciprocatory bar 6, whichconstitutes what will be termed a spring-retraction presserbar. Thepresser-bar is provided 'at its in- Serial No. 157.296. (No model.)

I ner end with'a bent portion or inclined engaging part 7, whichcoperates with the sleeve 8 to extinguish the flame when this becomesnecessary. The sleeve 8 is preferably of tubular form, though any othersuitable means of analogous character may be substituted for the samewithin the sphere of our invention. The presser-bar 6 is provided at itsouter end with a finger-piece 9, by which same is manipulated. Betweenthe fingerpiece9 and the finger-piece 5 of the shaft 1 is interposed acoil-spring 10, which is disposed about the bar-6 and serves to hold thepresser-bar normally in an outmost position. The finger-piece 9 of thepresser-bar is preferably revoluble, so that should same be seized bymistake for the purpose of raising or lowering the wick no damage willbe suffered by the attachment. Projected from the lower portion of thesleeve 8 is an extension 11, which extension covers a lateral lug 12.This lug is inclined and cooperates with the inclined portion 7 of thepresser-bar to raise the sleeveB when it is desired to extinguished theflame. The presserbar 6 is guided in its movement by a pair of lugs 13,disposed upon the base of the burner, which lugs engage the presser-barupon either side of the upturned end portion thereof and serve toprevent any lateral movement of the inclined end 7, so that thisinclined end is assured a movement which will also cause cooperationwith the lug 12, projected from the extension 11 of theextinguisher-sleeve. This is deemed of some importance to the practicalembodiment of the invention.

In the operation of the attachment to extinguish the dame, thepresser-bar being in its outermost position, it is but necessary toexert a pressure upon the finger-piece 9 to force the presser-bar 6inward. This causes the inclined end portion of the said bar to rideinto engagement with the lug 12, this movement causing subsequentvertical'movement of the extinguishing-sleeve 8. Removal of the pressureupon the finger-piece 9 permits same to resume its normal position underthe induence of the spring 10 in a manner which will be readilyapparent.

The attachment involves a decided simplicity relative to the number ofparts used, and consequently the cost of manufacture is reduced to thesmallest degree consistent with proper material and otherconsiderations.

Having thus described the invention, What is claimed as new is l. In anattachment of the class described, the combination with a lamp-burner,of a wick-tube, a spring-retracted presser-bar disposed for reciprocalmovement upon the bu rner, an inclined engaging portion disposed uponthe presser-bar, extinguishing means disposed adjacent the wick-tubeaforesaid, and means extended from the aforesaid eX- tinguishing meansadapted for coperation with the inclined portion upon the presser-barwhereby the Iiame may be extinguished.

2. In an attachment of the classdescribed, the combination with aburner, of a hollow Wick-raising shaft disposed thereon, aspringretracted presser-bar disposed for reciprocal movement within thewick-raising shaft, an inclined engaging part disposed upon thepresser-bar, guide means cooperating with the presser-bar to direct themovement of the aforesaid inclined portion, and an extinguishing-sleevedisposed adjacent the Wick-tube and coperating with the inclined portionof the presser-bar.

3. In an attachment for burners and the like, the combination with asleeve disposed adjacent the wick-tube, a hollow wick-raising shaft, aspring-retracted presser-bar disposed within the shaft for reciprocalmovement, an extension projected from theextinguishing-sleeve aforesaid,and an inclined engaging part provided upon the presser-bar forengagement with the aforesaid extension and for actuation of the sleeveby such engagement.

4. In an attachment for burners and the like, the combination with awick-tube, an extinguishing-sleeve disposed about the said tube having alug projected therefrom, a hollow wick-raising shaft, a spring-retractedpresser-bar disposed for reciprocal movement within the said shaft andhaving its inner end bent upward to form an inclined engaging portionfor coperation with the lug projected from the extinguishing-sleeve.

In testimony whereof we affix our signatures in presence of twowitnesses.
